I usually just wrap my wrist and put on my old shoes or no shoes then I hit the bag. Literally. I start out faster doing combos and trying new stuff then I slow as I get more tired. When I slow down is when I do my things the I know like the back of my hand. Then right before I stop I practice palm strikes cause usually my knuckles are sore cause I just wrap my wrist not my knuckles.. I usually do a little on the tree by my bag to make my hands tougher and do my "ending" strikes on the bag. I say ending cause its the ending of a fight and the ending of an opponents life I hit them right.
